Clinical Classification Guidelines
Medical Intelligence & Overview
Tuberculosis (TB) is a bacterial infection primarily known for affecting the lungs. However, it can also spread to other parts of the body, causing what is known as extrapulmonary tuberculosis. When TB infects organs other than the lungs but doesn't fit into more common categories, it's classified under ICD-10 code A18.8, which refers to tuberculosis of other specified organs. This condition requires careful diagnosis and management due to its potential to affect various tissues and systems within the body.
